Everest's Spring Clean Up

Twenty climbers set off to Mount Everest to try and remove decades-old garbage from the mountain in the world's highest ever clean-up campaign.

Many climbers have cleaned Mount Everest in the past but no one had dared to clean above 8,000 meters, an area known as the "death zone" for the lack of oxygen and treacherous terrain.

The climbers will risk the zone's thin air and freezing temperatures to pick up empty oxygen bottles, gas canisters, torn tents, ropes and utensils.

The mountain has become known as being the world's highest garbage dump. Many climbers leave their gear and trash behind as they descend due to exhaustion. The team hopes to bring down at least 2,000 kg of garbage.
